The AirTAC AirTAC GFR600-25 Filter Regulator, G1 (1 in) Port is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600-25 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your setpoint in a single body. This size 600 unit has a G1 (1 in) G-thread port, the standard 40 um filter element, and a differential-pressure drain that discharges collected condensate whenever the pressure drop across the element rises, with no operator action needed. With this drain configuration the regulated output is adjustable from 0.15 to 0.9 MPa (20-130 psi). The bowl on the 600 size is aluminium alloy, an external round gauge with a psi scale is fitted for setpoint reading, and the J code means no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and catalogue options include a 5 um element (code W), automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and NPT thread variants. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). Air must not freeze in the unit. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Filtering and regulating the compressed air feeding spray guns and air balancing lines in a paint booth, where clean air and a steady, visible setpoint keep finish quality consistent.
Conditioning the air that drives pick-and-place and carton-sealing cylinders on a packaging conveyor, with the round psi gauge giving operators a clear pressure reference at the line.
Supplying filtered, regulated air to pneumatic clamps and tool-change actuators on a machining centre, with the 40 um element cleaning the air ahead of the regulator in the same body.
Every meaningful choice on this family is decodable from the code. Step size and port to match your line: this is size 600 with a G1 (1 in) G-thread port, the largest step in the range. Drain type here is differential-pressure (codes A and M give automatic and manual); filtration is the standard 40 um element, with 5 um available as code W; the fitted gauge is the external round type reading psi, and MPa or bar scales can be specified instead. Thread is G on this unit, with PT as the standard and NPT orderable, and the J code means no mounting bracket. Flow is published as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your flow and pressure requirements and we will confirm the datasheet figures for this 1 in unit before you order.
This unit's drain discharges collected condensate when the pressure drop across the filter element rises, with no operator action needed. Automatic (code A) and manual (code M) drains are catalogue options on the GFR family if your installation needs a different arrangement.
